Abstract (en)
[origin: US2021068865A1] This disclosure relates to apparatuses and methods for preventing the onset of surgical complications and improving patient recovery from surgeries such as mastectomies, herniorrhaphy or hernioplasty. The apparatuses and methods using the apparatuses leads to improved outcomes from chest surgeries to treat hemothorax and pneumothorax. and progression of complications following minimally invasive surgery such as laparoscopic surgery. In one example, a leaf-like polyurethane heat-sealed bilayer that surrounds a plurality of wedge-shaped foam strips that join at a collecting foam portion inside a trocar is subjected to negative pressure provided through silicone tubing which is sealed to the perforated collecting foam portion. Such negative pressure applied for a prolonged period during or after closure of the chest or abdomen laparoscopic surgery, helps prevent fluid loss, abscesses, hematomas, seromas and infection, surgical complications which, in turn, enhances patient recovery, and reduces the length of their hospital stay.
